ASM_MOV_INT: power options, never never

Default avatar.png hejamandajiri: set it to never sleep and unplug your input devices and the ports lol

StevenV: Hello guys, do you guy know when will the green-circle got publised?

StevenV: As It isn't in community contribute section anymore

kovi: because it is in multiplay already

GroutchKeu: o/

Default avatar.png SirGouki: as others have stated, you can set your power options to never sleep/hibernate or autoshutdown, then hold the windows key and press L to actually lock the computer.

**PatrickMcGinnisII yawns

derjack: :upside_down:

Darleanow: Power of thor 2 is so fun to do

Default avatar.png MarkosTh09: hey

Default avatar.png deavani55: hello

d57c428df5ac317680a42d608ffb1652: how to close world chat

5DN1L: Thibaud on the forum: The removal of chat should happen next week.

Default avatar.png Aldoggen: :sniff:

Default avatar.png Bleson: (╯°□°)╯︵ ┻━┻

Default avatar.png **Bleson is stupid

wlesavo: 5DN1L :frowning:

Westicles: It will be funny when every Friday they push an update and it reappears

jacek: the chat will be available to everyone

Uljahn: should be possible to make invite-only community xmpp server

5DN1L: I think CG's concern is more about ongoing maintenance

jacek: the ongoing what

5DN1L: ongoing trolling :shrug:

5DN1L: dedicated trolling to keep the chat alive

5DN1L: or maybe i mean maintenance

5DN1L: :shrug:

jacek: :taco: 5DN1L

jacek: :(

5DN1L: thanks anyway :)

Default avatar.png Lavashyk: How to know the position of Thor?

5DN1L: you get his initial position from inputs

5DN1L: afterwards you have to keep track of it by yourself

Default avatar.png Lavashyk: Oh I see, thanks ;)

5DN1L: np :)

jacek: Automaton2000 where you will be next week?

Automaton2000: what is the most active

Westicles: Automaton2000 are you ported to https://cheloniangall.com/

Automaton2000: ok, i have a hard time

jacek: :smirk:

wlesavo: poor Automaton2000

Automaton2000: makes me want to puke

wlesavo: i feel you

jacek: oO

Default avatar.png feignbird: https://py-ground.netlify.app/

jacek: hm?

j4at: What will happen to you after they delete the chat ? Automaton2000

Automaton2000: had 2 energy drinks yesterday, feeling the drain

jacek: oh my

Joey_G: Automaton2000

Automaton2000: i am new to coding

Default avatar.png AndreyXD: same

Default avatar.png AndreyXD: I am learning Python rn but wanna learn C

NightScap3: RIP Chat

NightScap3: Byebye

jacek: C, python? quite different ;v

TheRipperJack: yea, i recommend c++ for starting

Joey_G: What does Automaton2000 think is the best way for starting?

Automaton2000: so might not just be your bot

Default avatar.png AndreyXD: No worries, learning only python. C is hard for me rn lol

therealbeef: the mirror match thingie is broken in the green circle multi. how do you report such bugs?

Astrobytes: Devs are at a conference currently, we await their return to possibly add proper leagues and mirror matches

eulerscheZahl: a firm wish, isn't it?

Astrobytes: Yeah :/

eulerscheZahl: the game remains crippled with so many top bots still missing

eulerscheZahl: 82 in the arena. vs 1700 in the contest

Astrobytes: Yes. Absolute travesty for such a nicely done game.

darkhorse64: you nail it, euler, without the best, the incentive is mostly gone

therealbeef: with only 90 matches and no mirror, and the first player advantage it's even more random at the moment

eulerscheZahl: if i would have missed legend in the contest, i still had a goal to achieve within the final contest leaderboard as a starting point

eulerscheZahl: now there is no such goal

Astrobytes: Yes, that's what affects darkhorse and myself

darkhorse64: ^

eulerscheZahl: just another dead multiplayer arena now. even if you start a game from scratch, more players mean more fun as you have a better way to track your own progress

eulerscheZahl: changed something, 50 ranks up. vs 1 or 2 up and not sure if random luck

Astrobytes: Yes, exactly.

Astrobytes: Corporate world sucks.

eulerscheZahl: at least the Fr supremacy is gone. almost as many japanese players now

Default avatar.png JBM: heya eZ, astroes, westies o/

Astrobytes: hey JBM, been a while :)

jacek: :upside_down:

struct: they will just open legend again and I will miss it again since it will be harder with even fewer bots

Gangbi34567: which chanel is for invite

Gangbi34567: whats the chanel name

Astrobytes: Chanel #5

darkhorse64: We have the PM now to help

Default avatar.png AliyTheEngineer: hi guys

Default avatar.png AliyTheEngineer: im new

Default avatar.png AliyTheEngineer: im beginner at js

struct: I didnt enjoy the game that much to go back into it

eulerscheZahl: What would be your strategy in the current Block the spreading fire puzzle event? How would you do in a Google-style interview based on the Wordle game? What do you think a coding problem from the World Championship Qualifiers look like?

struct: That question is for who eler?

struct: euler*

eulerscheZahl: i just got it in an email from CG

Default avatar.png AliyTheEngineer: how do i go to another test case

eulerscheZahl: promoting their youtube https://www.youtube.com/c/Codingame

Default avatar.png AliyTheEngineer: like to the 2nd

jacek: " Chat removal 💬 For maintenance reasons, we're sunsetting the integrated xmpp chat in favor of a unique place that part of the community already uses, Discord. Feel free to tell us what you think about the change in this forum thread."

eulerscheZahl: what nice and positive words to describe this sad event

Default avatar.png AliyTheEngineer: aww man

Default avatar.png AliyTheEngineer: no more chat

Astrobytes: AliyTheEngineer: complain here https://forum.codingame.com/t/discussions-spaces-update-the-question-of-the-chat/196276/10

Default avatar.png AliyTheEngineer: i didnt complain tho

Astrobytes: "aww man" sounds like disapproval to me ;)

jacek: nyoro~n

struct: "The removal of chat should happen next week."

struct: oh well

struct: I don't think people will just move to discord

struct: I think they might have the wrong idea

jacek: people think this is discord

eulerscheZahl: it is not?

struct: This chat probably has more messages in 1 month than discord has in 1 year

j4at: Codingame will never feel the same without chat, worst decision ever

j4at: What about pm and coc chat ?

struct: all removed

j4at: BRUH!

j4at: Why are they removing it tho ?

therealbeef: 1. costly to maintain, 2. the spam, 3. discord as alternative

Default avatar.png Aldoggen: I haven't seen spam in like a week

therealbeef: (just copying CG's message from the forum, not my opinion)

Default avatar.png Aldoggen: all right

Default avatar.png Revisto: HELLLLO

struct: Thats because there hasnt been spam in like 1 month

j4at: Chat with spam is better than no chat. Discord is not the same. I don't think that chat is costly to maintain!!

j4at: compared to the games atleast

struct: I probably averaged 1 ban per week last month

AryanTripathi: sup

Default avatar.png DevMarcao: this chat here will be removed?


Ayza: yes

struct: https://forum.codingame.com/t/discussions-spaces-update-the-question-of-the-chat/196276/9

struct: You can always leave your opinion on it

Ayza: discord is no different to be honest

Ayza: only difference is you can delete messages

Ayza: which can probably be easily made here

Default avatar.png DevMarcao: yeah but clash chat rooms are nice, i don't think they can be the same on discord

j4at: I don't want to use discord it's partially owned by the ccp :)

Ayza: yeah, I definitely don't want the chat to be deleted

Ayza: faster and easier to communicate while doing a puzzle

Ayza: instant response

Astrobytes: make sure you express your opinion in the forum thread :)

j4at: I can make a new chat for CG for free, and even put some backdoors.

j4at: jk about the last part

Westicles: hey, where's our clash type detector script?

j4at: I lied Westicles

Ayza: open source chat on top

Westicles: j'accuse!

Westicles: holding steady at 6 1-stars

j4at: Yeah, didn't find a way to to detect the type of the clash. I thought I did but I was wrong I just got lucky :p

struct: 44 more

struct: you are not wrong

struct: there is a way

j4at: how struct ?

struct: playClash request gives it

j4at: no it doesn't

struct: it does

struct: I just checked

Westicles: :popcorn:

j4at: it always return shortest

struct: oh then im wrong

eulerscheZahl: the word "shortest" is actually longer than "fastest"

Astrobytes: Valuable knowledge.

j4at: probably not even related to the mode of the game, but length of the game probably. Maybe they were going to add long clashes

eulerscheZahl: and i just told everyone, i really can't keep anything to myself :(

Astrobytes: :D

eulerscheZahl: in the past there were 2 clash durations i think (was before my time)

eulerscheZahl: 5min and 15min or so

eulerscheZahl: CG veterans like JBM can tell you

Westicles: they sunsetted the 5min

eulerscheZahl: they kept the easy ones as clash and moved the rest to community puzzles

Default avatar.png Aldoggen: tbh I like 15 minutes more. I almost never need it, but when I do, it's a godsend

eulerscheZahl: for shortest you need 15min or you are playing it wrong

Westicles: I was surprised, I had a sort of tough clash approved yesterday

StevenV: when will green-circle show up as a multi?

Westicles: yesterday

struct: its already a multi

Astrobytes: -ish

StevenV: oh

Default avatar.png Aldoggen: what version are they on currently?

Default avatar.png Aldoggen: I've seen low 50s

Westicles: free xp as the fr say

StevenV: thanks guys, I think that it would be on the top as always

eulerscheZahl: CG even mentioned it in an email an hour ago

StevenV: ah, I don't often check email

eulerscheZahl: i have thunderbird running all the time

StevenV: I've never used thunderbird

j4at: I'm thinking of creating 3rd party clashes, with custom puzzles and modes.

StevenV: don't even know what it is actually

eulerscheZahl: you can select the mode (and language?) in private clashes

j4at: I mean extra modes

j4at: custom modes

eulerscheZahl: like prettiest code?

Astrobytes: longest

j4at: no!

eulerscheZahl: closest to emoji in code layout

Astrobytes: Poetry?

j4at: I will add brainfuck to list of languages :)

Astrobytes: 1 hour time limit

eulerscheZahl: https://www.cise.ufl.edu/~manuel/obfuscate/pi.c

Astrobytes: lol

Astrobytes: Westicles: :rofl:

Westicles: what?

Astrobytes: forum thread response

eulerscheZahl: the troll puzzle?

Astrobytes: "I worry MAU metrics will be impacted as account banning and re-ups should drop drastically."

eulerscheZahl: oh, a new one

Westicles: well, that one guy must have made 10k accounts

eulerscheZahl: :D

Astrobytes: Classic response :D

Kellthazar: so, will this chat be terminated?

Default avatar.png DevMarcao: yes

Astrobytes: Please express disapproval here: https://www.codingame.com/forum/t/discussions-spaces-update-the-question-of-the-chat/196276/10

Default avatar.png DevMarcao: https://forum.codingame.com/t/discussions-spaces-update-the-question-of-the-chat/196276/9

StevenV: :D

Astrobytes: Since they asked for opinions

StevenV: I really like this chat actually

StevenV: so green-circle doesn't have the red league :(

Kellthazar: sad that the chat will end, but I understand the reasons for it. Maintain a bloated functionality is a nightmare in most cases.

StevenV: we can just keep the chat and won't maintain it :D

StevenV: well there are me and boss2 only :D

BrunoFelthes: no more leagues than wood for green circle?

JosiahWI: The featured event says to get help and help your peers directly in the chat? Does that refer to this chat or another one?

Default avatar.png Aldoggen: lmao

Default avatar.png Aldoggen: Thibault be like: ok lemme just get one of the other unupdated pieces of **** I've been carrying in my pocket for all these years

eulerscheZahl: https://www.codingame.com/training/hard/code-your-own-automaton2000-step-1 this puzzle will have to be rewritten

eulerscheZahl: Do you know Automaton2000? You don't? Okay, so, let's join the chat. Look at the right of the website and join the general channel. If you are level 3, just say "Hi Automaton2000" and the bot Automaton2000 will answer you.

Automaton2000: also i need to get it

Automaton2000: that's the way to go

Default avatar.png creeper82: Hi Automaton2000

Automaton2000: i am new to coding

struct: Bye Automaton2000

Automaton2000: when i have the same issues

Default avatar.png creeper82: lol Automaton2000

Automaton2000: i will try to learn it

StevenV: Hi Automaton2000

Automaton2000: but no need to worry about it

Default avatar.png creeper82: well ok? lol

Default avatar.png HenroLST: Hi Automaton2000

Automaton2000: that one is a bit weird

Default avatar.png HenroLST: :(

Default avatar.png creeper82: Hi Automaton2000

Automaton2000: what is your best friend

Default avatar.png creeper82: uhh. you?

Default avatar.png creeper82: nah just kidding you're a stupid bot

Default avatar.png HenroLST: ay

Default avatar.png HenroLST: dont be rude to my boy Automaton2000

Automaton2000: but there is no way to get an idea of what i do ;-)

j4at: Automaton2000 is tricking you humans and soon will takeover. As he said we have no idea what its doing.

Automaton2000: you can just take the first move

Default avatar.png HenroLST: dang he even wants you to take the first move

Default avatar.png Aldoggen: Automaton2000 how are you doing?

Automaton2000: oh so i cant do anything

Default avatar.png Aldoggen: clearly not so well

Daporan: I'm impartial, but if you really want the chat to stay then a last resort could be to tweet the forum thread to https://twitter.com/coderpad

j4at: poor Automaton2000! we need to build a body for it

Automaton2000: if i ever get to the top

Default avatar.png HenroLST: Automator2000, reply if I'm your favorite here

Default avatar.png HenroLST: NOOO I MISSPELLED

Default avatar.png Aldoggen: XD rip

struct: Enough of Automaton spam

Default avatar.png HenroLST: :(

Default avatar.png Aldoggen: tip: you can tab-complete names

struct: Time to ask jp to tweet since I dont have 1

5DN1L: Does CG earn any revenue from this part of the website? Or just from CodinGame for Work?

Default avatar.png Aldoggen: I tried to find something about that in the about of this website

Default avatar.png HenroLST: I guess its fianlly time to make a twitter account

Default avatar.png Aldoggen: nothing afaik

5DN1L: financial incentives would convince CG more than other factors, I guess

Default avatar.png Aldoggen: I believe there's a hidden financial incentive for keeping the chat

Default avatar.png Aldoggen: community

Default avatar.png HenroLST: true

Default avatar.png HenroLST: chats are supreme

5DN1L: you can't just tell that to the CEO :shrug: you need numbers and evidence

Default avatar.png Aldoggen: so even if the current one gets removed (cause I can understand no one wants to work on this thing, it was made by an intern long ago), I hope they add a new one

j4at: Make CG pay to win

Default avatar.png HenroLST: wait really? thats cool

j4at: Easy money

Default avatar.png HenroLST: clash of code but you can buy powerups

Default avatar.png Aldoggen: yup, that's part of the problem. I don't now anything about finance lol

Default avatar.png HenroLST: minus 1 min = $5

struct: pay 1$ per month to access chat

struct: done

Default avatar.png HenroLST: ... or that

Default avatar.png HenroLST: but powerups

Kellthazar: Hi Automoton2000

j4at: pay 5$ per month to get emotes

Kellthazar: Hi Automaton2000

Automaton2000: he is a real problem

Default avatar.png Aldoggen: XD

Default avatar.png HenroLST: pay for access to automoton and upgrade him

FrancoRoura: How can a chat become so expensive for a company like CG to think it's worth it to invest time in taking it down lol

FrancoRoura: You literally need like 500MB ram on a Redis and wss

struct: I dont think its expensive to run it, but to maintain or add features

struct: but im not sure

FrancoRoura: Tbh if it's not generating any benefit I'd just leave it as is and "abandon" it

5DN1L: abandon = don't complain when pastebin breaks or chat disconnects :shrug:

j4at: The chat makes money for the chat. Because it makes people participate in the sponsored events. right ?

j4at: for CG* :3

Default avatar.png HenroLST: or just watch ads start appearing in chat, or like watch an add for 30 min of chat

Lassassin: how to increase fontsize of editor and console inside of codingame?

StevenV: I like the active of you guys here on chat

Default avatar.png HenroLST: :)

StevenV: so if you guys active on discord, np for me :D

Default avatar.png Aldoggen: Lassassin there's a settings button on the left

Default avatar.png Aldoggen: then press edit configuration

Lassassin: thanks

Default avatar.png Aldoggen: np

Lassassin: what about the one in console output?

Lassassin: bottom left

Default avatar.png Aldoggen: I don't see settings there. for me they're in the vertical bar on the left

Default avatar.png Aldoggen: maybe we're just talking about the same thing

Default avatar.png HenroLST: uh im not sure if you can change the console output

Default avatar.png Aldoggen: oh, console?

Default avatar.png Aldoggen: hmm

Default avatar.png Aldoggen: nope

Default avatar.png HenroLST: whoaaa i can give brackets color

Default avatar.png Aldoggen: hey CG, what about fixing font resizability on your website instead of deleting chat?

StevenV: The best solutions are revealed>>

StevenV: so they will publish the solution for the optimation game?

j4at: no

StevenV: so what actually they do?

StevenV: "The best solutions are revealed" this is on the feature optimization puzzle, what does this mean?

5DN1L: unfixed text

StevenV: ???

5DN1L: that description should have been removed

5DN1L: but actually remains there

StevenV: ah, thank; you

5DN1L: np

StevenV: most of tops of multi are C++, does it mean C++ is faster than Rust on CG?

jacek: or no one knows rust

StevenV: :D

StevenV: I am gonna use Rust or C++ to solve multi on CG

struct: c++ is slow on cg

StevenV: I know C++ but not effictient enough to write a good bot and simultion

Astrobytes: because it's not in release mode, there are tricks to make it run faster

StevenV: maybe I should learn Rust

jacek: learn iron and oxygen first

Astrobytes: *learn chemistry first

5DN1L: https://en.wikipedia.org/wiki/Oxygene_(programming_language)

StevenV: I'll keep in mind that when starting to learn Rust

Default avatar.png Wishbone: Or if you want to learn something more entertaining but less useful, try learning brainfuck ;-)

StevenV: :(

StevenV: I would stay away from that

Default avatar.png Wishbone: Hehe, esoteric programming languages can be quite fun to mess around with.

eulerscheZahl: i recommend CG Funge

Astrobytes: Was about to recommend that, plus Code of the Rings or whatever it's called now, and there are a few BF/funge puzzles too iirc

StevenV: apart from fun, what is the point to learn those languages ?

eulerscheZahl: brainfork

Astrobytes: brain exercise ;)

Default avatar.png GoodGoodNotBad: Little noob question :sweat_smile:. Is there a reason why I can't call functions declared outside of main in main? Are they not both in a class by default? (c++).

eulerscheZahl: missing forward declaration?

eulerscheZahl: do you define the function after main()?

Default avatar.png GoodGoodNotBad: oh god I did

Default avatar.png GoodGoodNotBad: thanks

jacek: oO

jacek: Automaton2000 where do you go

Automaton2000: you probably have to rewrite my code to make a bot for it

Lassassin: goddamn there is no spoon more like there is no hope ._.

jacek: hm?

Lassassin: there is no spoon my brain tells me to write loops its mixing everything up

Lassassin: so many loops

Default avatar.png JBM: c++ has nested functions now?

jacek: lambda?

Default avatar.png 2wenty2wo: yeah lambda func

Default avatar.png JBM: good catch

Default avatar.png JBM: anyhoo, they're most certainly not in a class by default

BrunoFelthes: why there is only 100 players at green circle?

Astrobytes: Manual resubmission, no proper leagues, no mirror matches...

BrunoFelthes: man, what is happening with CG?

Astrobytes: devs were at a conference apparently, we'll find out next week if they add leagues or not I guess

aCat: soo even no chat to complain about it :(

BrunoFelthes: are they bank bankrupting?

aCat: *soon

Astrobytes: Since this was half-corporate and half-community, there are corporate contractual issues

Astrobytes: aCat: please post in the forum thread, even if it's purely for posterity

Astrobytes: https://www.codingame.com/forum/t/discussions-spaces-update-the-question-of-the-chat/196276/18

Astrobytes: They did ask for opinions after all ;)

struct: Yeah, leave a comment about it, even if its repetitive

struct: Its not like it can hurt

Astrobytes: there are also only 2 cats in there, we need more :P

Astrobytes: BrunoFelthes: you know they were taken over by an American company right?

Default avatar.png JBM: oh, taken over?

Default avatar.png JBM: I only read the PR about a merger, this is interesting

Astrobytes: By CoderPad yes

Astrobytes: 'merger' lol

Default avatar.png JBM: keep talking

jacek: its all about :money_with_wings:

Astrobytes: what a time to ask! struct help me out here, I'm ducking in and out of chat here

Default avatar.png JBM: seriously, tell me more!

struct: help with what?

jacek: Astrobytes soon youll wont have that problem

Default avatar.png JBM: I just saw the bland “we're moving in the same direction, let's do it together” kind of shit

Astrobytes: The coderpad takeover struct

struct: ah yes

struct: they bought CF

struct: CG*

struct: https://coderpad.io/about-us/coderpad-acquires-codingame/

Default avatar.png JBM: source?

Default avatar.png JBM: ah nice

mlomb: what

struct: this is old news

mlomb: didnt know

jacek: :ie:

jacek: hum

Astrobytes: struct JBM has been away for a lil bit

struct: I see

Default avatar.png JBM: Cookies on CoderPad: Accept or… no other option

struct: Bruno goes straight to the point lol

Default avatar.png JBM: well I did read the CG-emitted mailing, but the change of tone here is a welcome addition to my attempt at an objective opinion

Default avatar.png JBM: > its acquisition of CodinGame, a first-class candidate assessment platform and global developer skill building community.

struct: They probably bought it for CG for work

Astrobytes: we were all intrigued but cautiously optimistic until we found the coderpad post iirc

jacek: acquisition by bigger corpo is mostly bad

Default avatar.png JBM: that is not at all what I considered CG to be when I joined

Default avatar.png JBM: didn't know it was bigger

eulerscheZahl: that's the last page coderpad acquired: https://www.adaptilab.com/

Default avatar.png JBM: the CG mails did make it sound like “joint forces”, assumed mostly same-sized

struct: brb

Astrobytes: there is apparently only one dev working on our part of CG at any one time

Astrobytes: This was either on the forum or discord

eulerscheZahl: i saw some open positions (cg hiring) - task description sounding like combining systems of cg + coderpad

Default avatar.png JBM: well thanks a lot struct, that was mighty eye-opening

Astrobytes: they recently got rid of the 'get a job' part here too, useless outside of FR iirc

Astrobytes: "think global!"

Default avatar.png Eandy11: have you guys done the N agents one

Default avatar.png Eandy11: given N agents, find the traitor

Default avatar.png Eandy11: that one

Default avatar.png JBM: if I knew which one was the traitor I wouldn't make a CG problem out of it

jacek: https://digest.bps.org.uk/2022/07/01/people-with-no-minds-eye-have-less-vivid-and-detailed-memories/

eulerscheZahl: you can also see that in the job titles of their recent hires

Astrobytes: lol JBM

Default avatar.png JBM: the only one I noticed was the “evangelist”

eulerscheZahl: growth marketer, growth assistant

Astrobytes: tbf they had tech evangelists before (I am still unsure of what the and uncomfortable with any meaning of that is)

eulerscheZahl: what even is a growth copywriter?

jacek: he comes up with new names for puzzles and games

Astrobytes: writing copy for growth. Bullshit marketing-focused blog posts?

eulerscheZahl: for the protocol: i'm not bashing on random people i don't even know. just pointing out that there is a surprising high amount of non-developers

Astrobytes: Welcome to corporation-land.

Default avatar.png JBM: copywriter sounds way nicer than homophone copyrighter

eulerscheZahl: there is also growth hacker and head of growth

Astrobytes: Dilute any meaning from your target, grow it based on invented marketing hype, sell.

Default avatar.png JBM: with all this growth-drivenness they still take decisions aimed at harming the actual community

Astrobytes: Wrong kind of growth.

eulerscheZahl: i think they changed some titles in general. "head of people & culture". i think she was HR before

Astrobytes: This whole side is essentially dead to them

Astrobytes: (the corporate masters I mean, not CG staff)

Default avatar.png JBM: s/HR/PC/ is a worldwide trend, nothing really specific to see here

eulerscheZahl: compared with wayback machine, definitely some job titles renamed

eulerscheZahl: https://web.archive.org/web/20200924024105/https://www.codingame.com/about/team vs https://www.codingame.com/about/team

Astrobytes: well you only have to look at cleaner == sanitationary technician

Default avatar.png JBM: that's clearer than what we used to have in {fr}

Default avatar.png JBM: «technicien de surface»

PatrickMcGinnisII: One of my GF's besties was a headhunter until CoV hit, then she moved to HR within a large company. I sat in on one of her interviews with an 'engineer' ... intelligent young man, yes ... coder, no. Headhunting is big $$, companies need solutions ... and frankly the US doesn't have the hardcore programmers. Alot of reasons for this (in general).

Default avatar.png JBM: there's really no more sanitation-related meaning to surface in {fr} as there is in {en}

eulerscheZahl: oh, mathis hammel gets a mustache on mouse-over on my last link :D

Astrobytes: It's descriptive yet exceptionally vague, interesting :D

Default avatar.png JBM: that's the evangelist, isn't it?

Default avatar.png Eandy11: how do you find the 2 numbers of something when you have the sum and product of those 2 numbers

Default avatar.png JBM: I'm sure I've read his name before, I've (still) got to dig

Default avatar.png Eandy11: im using Javascript

Default avatar.png wagabond12: hey, how can i join clash of code with my friends, to a global lobby ?

Default avatar.png Eandy11: no clue what to do

Astrobytes: try writing out on paper, or whiteboard to save trees

Default avatar.png HenroLST: you could use algebra

eulerscheZahl: he's active on some competitive platforms like codeforces

Default avatar.png HenroLST: x+y=sum; xy = mul

Default avatar.png JBM: not sure whiteboard actually saves trees compared to paper

Default avatar.png HenroLST: then you just manipulate those equations to get what you want

Default avatar.png JBM: active, but noteworthy?

jacek: https://www.nagwa.com/en/videos/249197026232/

Astrobytes: Depends what you use as a pen and whiteboard JBM, though true

Astrobytes: Lets all get active on other platforms then CoderPad might hire us for CG....

Astrobytes: ...

Default avatar.png JBM: that better than CG hiring you directly?

eulerscheZahl: let me invite you to topcoder if you like optimization tasks

Astrobytes: Not sure :thinking:

Default avatar.png JBM: pretty sure I;ve already got a dormant acct there

Astrobytes: yeah I think you might enjoy some of the TC marathons JBM

eulerscheZahl: if you want to get hired: https://www.welcometothejungle.com/fr/companies/codingame

Default avatar.png JBM: I might if I had that OM of time available

Default avatar.png JBM: I know some of those faces

Astrobytes: at least that site has a cookie rejection button

struct: I think they must

struct: according to EU law

Default avatar.png JBM: ha ha “office manager” and I do think I read it on CG first

Default avatar.png JBM: darn my console got utf8ucked between two screen -r invocations

Default avatar.png JBM: hope it's better on your side

PatrickMcGinnisII: dotconferences...nice... why so many vids on Swift?

jacek: hm? ̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤

eulerscheZahl: i'm not sure if the cookie reject works as it's supposed to open this in an incognito window: https://www.codingame.com/forum

eulerscheZahl: then click refuse. it will reload the whole page

Astrobytes: other than a few †it's OK JBM

eulerscheZahl: shouldn't it be the other way? load something extra when you accept

Default avatar.png JBM: those were qmarks

Default avatar.png JBM: the proper ones, y'know

Astrobytes: I worked that one out

Default avatar.png JBM: never settle for… oh well

jacek: Automaton2000 do you know any utf trick?

Automaton2000: this is a test ' by struct

Default avatar.png JBM: it's f8cked on my side, it's f8cked on yours

Default avatar.png JBM: what does the stream think it's doing

eulerscheZahl: jacek trolled us

struct: Automaton2000 I'll ban you before chat gets removed

Default avatar.png HenroLST: panic why is there a line of 2 minature dots going through the middle of my chat

Automaton2000: is it possible to reach legend

struct: ...

jacek: oh my

PatrickMcGinnisII: help us Automaton2000

Default avatar.png HenroLST: wait what the its scrolling with the chat

Automaton2000: to get the best move

struct: Maybe I should pin the post :D

eulerscheZahl: abuse your mod powers, i'm all for it

eulerscheZahl: i abused mine to get the hypnotoad title on the forum

Astrobytes: And I have my 5%

struct: Well it's not like I will remain a mod if chat is gone

Default avatar.png HenroLST: ... uh oh

Jay10890: anyone got the answer to mars lander episode 2

Astrobytes: 12

Jay10890: got answer to mars lander ep 2?


struct: Done

Jay10890: struct do u got it?

struct: oh I never done mars landers 2

eulerscheZahl: he pinned a forum post

Astrobytes: 42

Jay10890: eular u got the code?

PatrickMcGinnisII: jay , like search github er somethin. 42 is the best answer

Jay10890: wym 42

eulerscheZahl: i got one code. there are almost infinitely many solutions

Default avatar.png HenroLST: 42: the answer to life the universe and everything

Jay10890: ok

eulerscheZahl: the only thing that prevents the infinite amount if the 100k code size limit

Jay10890: euler how long as it been

eulerscheZahl: i don't understand

Jay10890: since we last met


eulerscheZahl: oh "has". no idea

struct: wait the other post that was pined is gone

struct: o.o

Jay10890: been months tbh

eulerscheZahl: if you are the one i think, not long enough

eulerscheZahl: pinned posts only show as pinned for you until you open them, struct

eulerscheZahl: try again in incognito, then it should be back to normal

struct: ah

struct: thanks

PatrickMcGinnisII: I'm gonna be in D.C. in 10 days, any advice?

eulerscheZahl: or you broke it :imp:

struct: well it was worth

struct: this topic is more important

BugKiller_328: @Astrobytes, @struct

struct: yes?

Astrobytes: hi BugKiller_328

BugKiller_328: I don't know who suggested me about iterative deepening. I've applied it to connect 4 and my ranking was upgraded from 79th -> 54th

BugKiller_328: in wood 1 league. thanks.

Astrobytes: possibly either or both of us

struct: nice

Astrobytes: and nice, well done :)

BugKiller_328: no 53th as final result

eulerscheZahl: might have been me. i was thinking about it but not sure if i spelled it out

BugKiller_328: with Java lang

jacek: :tada:

struct: now implement bitboards :)

jacek: and do you use ordering while iterative deepening?

Astrobytes: PatrickMcGinnisII: Well, from DC you can tell us if it's better than AC

eulerscheZahl: jacek wrote it, credits to him

BugKiller_328: maybe need to migrate java to c++?

eulerscheZahl: https://cg.spdns.eu/wiki/Chat:World/2022-06-29

struct: you can try BugKiller_328

Astrobytes: lol, nice one euler

BugKiller_328: Ah, @jacek Thanks

BugKiller_328: I think @jacek @Astrobytes, @struct you all! thanks again

struct: np

Astrobytes: you are very welcome

eulerscheZahl: use the chat to your advantage

BugKiller_328: @jacek "and do you use ordering while iterative deepening? " what is this?

eulerscheZahl: you have good and bad moves from minimax

Astrobytes: move ordering

Astrobytes: try the best one first

eulerscheZahl: as you have pruning, the order matters. apply the best first to prune more

Jay10890: i found this\

Jay10890: http://chat.codingame.com/pastebin/e5ca7c25-3f43-4516-9564-dd0435c9ed43

eulerscheZahl: no you didn't find it

BugKiller_328: how to ordering for my available moves.

Astrobytes: It's an advantage of iterative deepening in that you know the best move from the previous depth searched

Jay10890: https://github.com/vadim-job-hg/Codingame/blob/master/MEDIUM/MARS%20LANDER/python/mars-lander-episode-2.py

Jay10890: this it?

eulerscheZahl: there is not this one correct solution. code your own

Astrobytes: ^

Jay10890: tried

eulerscheZahl: try harder

Astrobytes: hence why your silly question got sill answers

Astrobytes: *silly

jacek: Jay10890 have you ran it

eulerscheZahl: or try another puzzle and come back later

Jay10890: yes

jacek: BugKiller_328 i.e. in chess you would try capturing moves first. in othello the corner moves

Astrobytes: Or learn something about the problem you are trying to solve, in order to better understand it

Astrobytes: @Jay10890

jacek: but with iterative deepening + transposition table, you can try the best moves from previous iteration

jacek: as they are likely to produce faster cutoff

jacek: http://blog.gamesolver.org/ and http://blog.gamesolver.org/solving-connect-four/05-move-exploration-order/ and http://blog.gamesolver.org/solving-connect-four/10-better-move-ordering/

Astrobytes: things like this are why I love this chat

eulerscheZahl: i wanted to download all chat logs and extract URLs but somehow never did

jacek: my youtube links? :smirk:

Astrobytes: well, the logs will remain I guess as long as dbdr doesn't remove them

jacek: hopefully after chat is removed theyll see significant drop in :moneybag: and bring it back

eulerscheZahl: unlikely, i see myself more as a cost factor for CG

Default avatar.png HenroLST: STRIKE

Astrobytes: I doubt that. They'll see a drop in use of the free side

Astrobytes: what euler said

BugKiller_328: @jacek do you have youtube channel? what's it?

Astrobytes: Personally, I think open-sourcing a lot of this side of CG would be a huge benefit

jacek: here we go https://www.youtube.com/watch?v=dQw4w9WgXcQ

Astrobytes: I know it won't happen but still

eulerscheZahl: https://www.youtube.com/watch?v=dQw4w9WgXcQ

eulerscheZahl: damn, too slow

Astrobytes: Yeah don't click that one BugKiller_328

BugKiller_328: Is MCTS much harder than alpha beta?

PatrickMcGinnisII: crap it's raining

eulerscheZahl: it's different

eulerscheZahl: but yes, takes a few more lines to code

Astrobytes: But if you understand alphabeta/minimax well it is easy enough to understand

eulerscheZahl: and it's hard to understand as a human what's going on. easy to code a bug and not even realize that it's wrong

Astrobytes: as euler says though, it's a little more work to implement

BugKiller_328: hmm, MCTS, GA, NN

BugKiller_328: what should I go first?

BugKiller_328: make an order for me

Astrobytes: get really good at alphabeta first

BugKiller_328: alpha beta already done

PatrickMcGinnisII: 11k pos / second... move ordering ... nah doesn't work great for CG

struct: 11k pos in php?

Astrobytes: move ordering, pv, null window, negascout etc? BugKiller_328

jacek: killer moves

PatrickMcGinnisII: 11k nope, more like 2k

jacek: and well GA is rather broad, it doesnt have to have anything with tree search

PatrickMcGinnisII: I think i did something similar for the bike race puzzle

BugKiller_328: I really like to know how to check isWin in connect 4

Astrobytes: history, fail high or low? TTs and all the fun that comes with them, the list goes on

Astrobytes: *fail hard or soft

eulerscheZahl: https://tech.io/snippet/Fbf9HIO MCTS for connect4. not optimized for speed at all

BugKiller_328: I have 4 for loops. 1 for horizontal, 1 for vertical, 1 for positive diagno, 1 for negative diagno

Astrobytes: well that's where bitboards come in

PatrickMcGinnisII: BugKiller_328 it's hard for CG version because of width and fitting it in 2 - 64 bit boards

BugKiller_328: anyone tried bitboard in Java?

eulerscheZahl: it's not different to bitboard in other languages

Astrobytes: Plenty people do

BugKiller_328: I'm asking this because as I remember,

eulerscheZahl: but be careful about shifting: java only has signed integers and thus >> and >>>

BugKiller_328: when I try bitboard in c++ in times ago

Astrobytes: I think some of the bitwise operations are slightly different in java but the concept remains unchanged

BugKiller_328: I used some c++ specific api functions

Astrobytes: intrinsics?

PatrickMcGinnisII: i think u have to make sure you don't get stuck in a 2's complement arrangement

eulerscheZahl: popcount

Nerchio: yeah you lack some nice functions to use bitset in java, and you're probably not going to be much higher than wala's places in those games (he's top30 in connect 4 with java)

Nerchio: even if you somehow optimized everything you can

BugKiller_328: __builtin_ctzl, __builtin_ia32_pdep_si, __builtin_popcountl

struct: top 20 should be possible

BugKiller_328: these kind of func

struct: out of those this is the only one I use for c4

struct: const U64 pdep = _pdep_u64((1ULL << rand(__builtin_popcountll(safe_moves))), safe_moves);

struct: to select a random set bit in safe_moves

BugKiller_328: @struct, do you have that kind of code for java?

struct: no

Astrobytes: Print it out, spill coffee on it [solved] :P

Astrobytes: afaik, C/C++/Rust are probably the ones you wanna use for bitboard-intensive stuff

eulerscheZahl: C# got better in that regards

BugKiller_328: c++ vs c# ?

eulerscheZahl: C++ still faster

BugKiller_328: c++ much faster than c#?

Astrobytes: I was about to add that I think C# might be better than Java too

BugKiller_328: or slightly?

eulerscheZahl: but C' has release more on CG at least

Astrobytes: *C#, mode

eulerscheZahl: yes

eulerscheZahl: # and ' are the same key with shift on my keyboard

eulerscheZahl: e.g. https://docs.microsoft.com/en-us/dotnet/api/system.numerics.bitoperations.popcount?view=net-6.0

Astrobytes: # and ~ here

eulerscheZahl: relatively new but i think you can use it on CG already

eulerscheZahl: and syntax-wise C# and Java are similar enough that you can switch easily

BugKiller_328: I know c, c++ too

jacek: remember they have uppercase methods names :unamused:

BugKiller_328: c, c++, c# a little, java (in depth more)

struct: if you want to learn bitboards choose c++

eulerscheZahl: and IInterfaces - the last bit of hungarian notation

Astrobytes: I would use the language you are most comfortable with then, that has the best features that you need

BugKiller_328: c++ not c?

Joey_G: It's PascalCase not Uppercase

struct: c++ its easier

BugKiller_328: but speed is similar?

struct: I think so

eulerscheZahl: UPPERCASE

Joey_G: right

struct: Speed its almost irrelevant on c4

BugKiller_328: again what about c++ vs c#

eulerscheZahl: but C# uses PascalCase

Astrobytes: Yes, speed is similar, be careful with using some standard containers though

BugKiller_328: c++ is much faster or slighly faster than c#?

eulerscheZahl: camelCase for private stuff

j4at: C# is a lot slower than C++

struct: for bitboards I would say much faster

Astrobytes: snake_case

eulerscheZahl: that's so python

Astrobytes: preferred in C++ too

struct: snake is how I code c++

j4at: python_case

Joey_G: IdIoTcAsE

Astrobytes: j4at: speed-wise he was speaking of C vs C++

eulerscheZahl: for java, c#, python i try to follow conventions. for c++ i never read a style guide :(

Kellthazar: Are you folks talking about the event?

eulerscheZahl: no

j4at: C are C++ are equal speedwise

Joey_G: rANdOmcaSE

eulerscheZahl: as long as you stay away from polymorphism

Astrobytes: And resizing std containers on the fly

Joey_G: Did anyone simulate CodeVsZombies?

Astrobytes: Most people with a decent score yes

Joey_G: I'm having trouble with reversing the targeting mechanics, I think there may be some issues?

Joey_G: Is there anyone who could perfectly predict the movement?

jzen: I think mine does, I'll check

struct: https://pastebin.com/VRNBF4ki

j4at: Python 3.12 will have a jit <:

jacek: so... pypy3?

j4at: I use pypy3 a lot for things. But it doesn't support tensorflow / pytorch.

jacek: hows your search race going

jacek: whats youre record on hold the line testcase

Astrobytes: straight to the point :D

struct: 9883

jacek: quite slow

Joey_G: Struct, can you show the implementation of distance(...) and distance2(...)

struct: inline int distance2 (int _x, int _y) {

   return (x - _x)*(x - _x) + (y - _y)*(y - _y);

}

struct: inline float distance (int _x, int _y) {

   return sqrt(distance2(_x,_y));

}

Joey_G: thx

struct: My bot is quite slow jace k

Joey_G: Are x and y global variables?

struct: zombie position

struct: and target

Joey_G: Got it

struct: its a class

struct: class Point { float x, y; float dist ... }

BlaiseEbuth: Geronimo!

Joey_G: "inline float distance (int _x, int _y)" gets called with "distance(dist2)" but dist is just an int. Am I missing something?

**BlaiseEbuth wait for the taco-hammer.

struct: might be an int yeah

waterproofsodium: somebody familiar with markov chains?

waterproofsodium: (stuck at a problem 2+ days straight, trying to educate myself on the topic)

BlaiseEbuth: Automaton2000 are you familiar with Markov Chains ?

Automaton2000: so when you do this

Joey_G: "inline float distance (int _x, int _y)" gets called with "distance(dist2)" but dist2 is just an int. Am I missing something?

Joey_G: Sorry for typo

Astrobytes: BlaiseEbuth :hugging:

waterproofsodium: I see I asked wrong time of the day. everybody is drunk (just kidding)

BlaiseEbuth: :hugging:

struct: Joey_G https://pastebin.com/gdJuW3DN

jacek: oO

waterproofsodium: I'm looking for resources, for programmers on markov chains btw

struct: this code is 5 years old

struct: dont judge :p

Joey_G: So it's overloaded. ty

jacek: markov chain? which puzzle

waterproofsodium: jacek it's for google foobar. non public

jzen: Probably 'Markov Text Generation'

jzen: By wonton

jacek: oh

waterproofsodium: nope not text generation

jzen: Oh

jzen: nvm

jzen: It's a good puzzle for learning then

waterproofsodium: I'm on a timer and the topics diverge slightly :D

Default avatar.png GlitchedPug: can someone help me the the tempertures puzzle?

jacek: eeyup

Default avatar.png GlitchedPug: ?

Default avatar.png GlitchedPug: yes?

jacek: we can help

waterproofsodium: he said

Default avatar.png GlitchedPug: ok

waterproofsodium: "eeyup"

Default avatar.png GlitchedPug: im new so im pretty bad at coding

Astrobytes: how far in to the foobar now waterproofsodium?

waterproofsodium: level 2

waterproofsodium: complete

BugKiller_328: in c++, hwo to get time in miliseconds?

waterproofsodium: level 3 is 3 puzzles 1 solved

BugKiller_328: time_point<steady_clock> now;

           now = steady_clock::now();

BugKiller_328: I can see this code, but which header I need to include?

waterproofsodium: and 5 in total

BugKiller_328: only chrono?

BugKiller_328: ah, I missed

using namespace chrono;

BugKiller_328: thanks

jacek: chrono

jacek: and namespace

jacek: oh

BugKiller_328: in c++, min int inf and max int inf?

j4at: jacek, CPython 3.12 will have a jit. The problem with pypy is that ML libraries doesn't support it :(

j4at: My hold the lnie record is 136.88 which is pretty slow

jacek: thats problem for those who use ML libraries :v

waterproofsodium: how can you compile python to jit? I bet only by torturing the JIT compiler

Astrobytes: min = -INT_MAX, max = INT_MAX if that's what you are asking

j4at: I use it for web hosting and video game servers.

jacek: j4at noice, my NN gets 150+

j4at: hehe non

j4at: noob

BugKiller_328: where's INT_MAX lives?

Astrobytes: climits? cstdint?

Astrobytes: can't remember

jzen: climits

BugKiller_328: Thanks a lot

Astrobytes: np

Astrobytes: cheers jzen

j4at: https://www.codingame.com/share-replay/648717335

waterproofsodium: hidden tests are mean

BugKiller_328: rand number for 0 to n?

Default avatar.png cyberPanda: hez

waterproofsodium: if hidden tests are good. they will make you fail when you didn't do your research :p

jzen: rand() % n

BugKiller_328: rand() will just from 0 ~ max int?

struct: j4at this is my personal best https://www.codingame.com/replay/641054548

jzen: Well, rand() gives you a random int from 0 to max, and when you take the modulo you will get a number in [0:n-1]

jzen: So yeah

Joey_G: Struct, your code is correctly working. Thank you.

struct: np Joey_G

jzen: n is non-inclusive however

j4at: yeah struct I already saw it, pretty impressive

Astrobytes: but you can make functions to change that if you need. Also, prefer even std random methods over rand()

struct: yours is NN right?

j4at: mine is NN

struct: do you use policy for moves?

j4at: yeah

j4at: RL, ddpg variant

struct: ok I have no idea what that is

struct: but im a NN noob

struct: all I know is input, hl and output

struct: :D

jacek: https://stable-baselines.readthedocs.io/en/master/modules/ddpg.html

jacek: one of those dqn, a3c, trpo, ppo stuff

struct: ah right

derjack: :s https://www.codingame.com/share-replay/648719553

j4at: derjack NN ?

jacek: yes

jacek: on my main i use GA search

struct: you should try the moves I allow as policy

j4at: It seems it doesn't like the number 4

BlaiseEbuth: Oh. j4at :o

j4at: :))

BlaiseEbuth: Was wondering who you was that guy... Well, one stranger less on cheloniangall... \o/

Default avatar.png JBM: which stranger would that be?

BlaiseEbuth: Well j4at ^^

Astrobytes: still loving that name :D

BugKiller_328: hi, simple question

BugKiller_328: how to change static variable of class

BugKiller_328: class A{

public:
  static short data;

};

Joey_G: ClassName.VariableName = newValue

struct: in c++ I know its A::data = 1;

BugKiller_328: int i; A::data = (short)i;

BugKiller_328: this gives me error

jzen: short A::data

jzen: You need type as well

Astrobytes: outside of the declaration

Astrobytes: short ClassName::data = 0;

struct: http://chat.codingame.com/pastebin/904eb5b5-bc76-491d-a908-3407352aacf7

struct: https://tech.io/snippet/IDCFgQC

struct: what astro said

BugKiller_328: not working. give me error like undefined reference

jzen: Surely you don't use the class keyword in your actual code struct :smile:

struct: i dont

struct: BugKiller_328 check what I wrote

struct: you need the thing that is between class and main

Blokops: any javascript user here? can someone explain in 20 words or less how to methods?

Astrobytes: how to methods: method

Blokops: interesting

Astrobytes: it made equal sense with your question ;)

BugKiller_328: https://pasteboard.co/BX8wXsi7YQxX.png

Blokops: how to make a method

struct: BugKiller_328 check the snippet I wrote

struct: you are missing

Astrobytes: @BugKiller_328: check structs snippet

struct: short A::data = 1;

struct: or w/e value you want

Astrobytes: OUTSIDE of the class and OUTSIDE of the main

BugKiller_328: short A::data = 1; how we can do??

Astrobytes: this is usually a header/definition issue but CG is different I guess

struct: https://tech.io/snippet/IDCFgQC

BlaiseEbuth: https://googlethatforyou.com?q=js%20create%20method

Default avatar.png Aldoggen: Blokops check out W3Schools. They're pretty good for explaining simple things

Blokops: im here because W3Scjhools are shit

Default avatar.png Aldoggen: well all right lets move to private chat

BugKiller_328: @struct I want to do it inside main function

BugKiller_328: because I can only know value inside main

struct: https://i.imgur.com/CtHOfPZ.png

struct: thats needed

BugKiller_328: ah, but why is it needed outside main?

BugKiller_328: why we need to initialize it once outside main?

Default avatar.png Aldoggen: the compiler needs to know what you're going to do

Default avatar.png Aldoggen: is the short answer

BugKiller_328: Can I do that inside class?

j4at: Blokops

j4at: http://chat.codingame.com/pastebin/e64c7120-4e23-49f4-a61b-646f319a2874

jacek: D:

j4at: https://pastebin.com/raw/ZYs6vjUD

Astrobytes: No BugKiller_328

Astrobytes: That is the point. That static variable must be initialized outside of the class

jacek: blashemy

BugKiller_328: hmm, I'm most comfortable in Java. and I only used c++ for algorithm solve.

BugKiller_328: so almost didn't use the class.

BugKiller_328: :(

BugKiller_328: maybe I don't know basics

j4at: is domi using NN in search race ?

struct: yes


jacek: domi?

struct: domiko

jacek: really?

struct: yes

struct: and in py3

struct: real python

struct: his csb is also NN

struct: and also py3

jacek: oh my

j4at: Don't worry soon enough I will pass him and pass recurse too

j4at: I had 10.9k NN but accidentally overwrote it. Needs to train again :(

struct: hardcoded?

j4at: Well kinda. I do a little search over my NN and use the best solution

j4at: struct I didn't use beam search like I told you I was going to do. I used pure reinforcement learning

j4at: hard coding sucks

Default avatar.png Aldoggen: seems like it'd be a good vacuum cleaner

jacek: :no_mouth:

Default avatar.png Aldoggen: oof all right I'll shut up

Blokops: the good thing of lerning a new language is that i can just copy my code golf and get free points

Default avatar.png ellen_lu: could someone help me on starting the "block the spreading fire?"

struct: check cg video ellen_lu

Blokops: the problem looks like Montecristo

Blokops: monte carlo

BlaiseEbuth: :3

Blokops: sayyyy does javascript also have an encoder as python?

Blokops: utf16(?) to utf8 sort of encoder

Blokops: nvm found one

BugKiller_328: hi

Blokops: hi

BugKiller_328: in connect 4, if depth is 0, I need to calculate heuristic

BugKiller_328: what is the best way for it?

Default avatar.png Aldoggen: check if the game is over maybe?

Default avatar.png Aldoggen: idk

BugKiller_328: no can't do that

BugKiller_328: need to estimate the score of current board (which is not finished yet

Default avatar.png Aldoggen: it might be finished if you search reaches depth 0

BugKiller_328: depth 0 means it reached depth limitation

Default avatar.png Aldoggen: I don't know a better heuristic sorry

BugKiller_328: in minimax, if I search with depth 4, then in depth 4

BugKiller_328: game can't be finished

BugKiller_328: which means, we need to try calc heuristic

Default avatar.png Aldoggen: my "heuristic" would just amount to almost random moves, except when it sees the game ends in 4 moves

Default avatar.png Aldoggen: so yeah I understand you don't want that :)

BugKiller_328: ah, you're doing random move?

Default avatar.png Aldoggen: nope

Default avatar.png Aldoggen: if I use as heuristic to check for the end of the game, I get what I wrote above. so most of the time just random moves, because most of the time the game won't end, which means most moves are equally fine for the bot

Default avatar.png Aldoggen: maybe a better heuristic is to look at the amount of 3 stones on a line?

Default avatar.png Aldoggen: amount of 2 stones on a line would be important too.

Default avatar.png Aldoggen: but for both of those, you should only count them when they're not blocked

Default avatar.png Aldoggen: maybe that can serve as a nice heuristic

BugKiller_328: I already to in that way. I'm in rank betwen 55 ~ 80

Default avatar.png Aldoggen: then I probably can't help you :)

Default avatar.png Aldoggen: good luck!

j4at: block the spreading fire best solution is to hard code it.

j4at: there is only few validators

struct: I dont do eval, I use mcts so cant help

BugKiller_328: @struct, can you give me some code for connect 4?

BugKiller_328: which is using bitboard

BugKiller_328: droppiece, check win

BugKiller_328: no idea clearly yet for bitboard use for connect 4.

BugKiller_328: if you can't , it's fine :)

Default avatar.png HenroLST: anyone willing to take a quick look at my code and see where it might go wrong? its the puzzle scrabble and i pass all but three cases

struct: Well it might be a little unfair for other players

BugKiller_328: ok, then :)

struct: I can show you how I apply a move and how I generate them

struct: But wincheck and such are avx and its probably not fair for other for me to share

BugKiller_328: yes. totally fine. I can understand. I can try myself for it.

struct: https://pastebin.com/wLLxRgbf

struct: thats about everything I will share

struct: Whats outside applies a random move

struct: to check for win you will need to use masks

struct: 0x7E3F1F8FC7E3F1F8ULL, 0x7FFFFFFFFFFFFFFFULL, 0x7E3F1F8FC7E3F1F8ULL, 0xFC7E3F1F8FC7E3FULL

BugKiller_328: ooo.. what a horrible numbers. haha

struct: its too prevent overlap

BugKiller_328: maybe need to take time for the experiences.

struct: so when I do >> 1

struct: I wont end up on bottom row

struct: since I wanted to check the piece on the right

struct: yes, I think there are better games to learn bitboards

struct: connect 4 is probably not the easiest one

BugKiller_328: need 2 board

BugKiller_328: 1 is for me

BugKiller_328: other is for opponent?

struct: yes

struct: thats what I do

BugKiller_328: lowest place to be (0,0)?

struct: for me 0, 0 is bottom right

struct: But that's personal preference

BugKiller_328: in board (0,0) is in most right side bit?

struct: 0, 0 is bit index 0

BugKiller_328: bit index 0 means most right side bit

BugKiller_328: am I right? :D

struct: I think so

struct: I would try something simpler first bugkiller

struct: probably normal tic tac toe to learn the bitobards

struct: its what I did to learn it

BugKiller_328: yeah, I did it fewmonths ago a little

BugKiller_328: but I came back to learn more

MAWAAW: Buy the rumor. Sell the news.

Darleanow: Night everyone :)

Darleanow: struct werent u mod ?

EzS-NoVa: hiiiiiiiii uwu
